[1.8][SOLVED] Bow FOV Zoom help

NovaViper · January 24, 2015

Hey I'm to get my custom bow to have that zoom that the regular bow has, but I have no idea how to do that. Here is my bow code (this is super class that extends to the ItemBow class and it used for multiple bow types)

public class ItemNileBow extends ItemBow
{
    public String elementType;
    
    public ItemNileBow(String type, int damage) 
    {
        elementType = type;
        this.setMaxDamage(damage);
    }
    
    @Override
    public ModelResourceLocation getModel(ItemStack stack, EntityPlayer player, int useRemaining)
    {
        ModelResourceLocation modelresourcelocation = new ModelResourceLocation(Constants.modid   ":"   elementType   "_bow", "inventory");

        //System.out.println(player.getItemInUse()  ":"   useRemaining); USE FOR DEBUGGING ONLY
        
        if(stack.getItem() == this && player.getItemInUse() != null)
        {
            if(useRemaining >= 71987)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid   ":"   elementType   "_bow_pulling_0", "inventory");
            }
            else if(useRemaining > 71980)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid   ":"   elementType   "_bow_pulling_1", "inventory");
            }
            else if(useRemaining <= 71976 || useRemaining >= 71976)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid   ":"   elementType   "_bow_pulling_2", "inventory");
            }
        }
        return modelresourcelocation;
    }
    
    public EnumAction getItemUseAction(ItemStack stack)
    {
        return EnumAction.BOW;
    }
    
    public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
    {
        net.minecraftforge.event.entity.player.ArrowNockEvent event = new net.minecraftforge.event.entity.player.ArrowNockEvent(playerIn, itemStackIn);
        if (net.minecraftforge.common.MinecraftForge.EVENT_BUS.post(event)) return event.result;

        if (playerIn.capabilities.isCreativeMode || playerIn.inventory.hasItem(Items.arrow))
        {
            playerIn.setItemInUse(itemStackIn, this.getMaxItemUseDuration(itemStackIn));
        }

        return itemStackIn;
    }
}

How do I do that though? I don't see anything to use from it

NovaViper · January 24, 2015

I did something like this:

public class FOVEvent {
    
    @SubscribeEvent
    public void FOVUpdateEvent(EntityPlayer entity, float fov)
    {
        if(entity.getItemInUse().getItem() == ModItems.nileBow){
            fov = 2f;
        }
    }
}

But the client crashes and gives this out:

What am I doing wrong?

NovaViper · January 24, 2015

Oops, my mistake, here's it is now:

public class FOVEvent {
    
    @SubscribeEvent
    public void FOVUpdate(FOVUpdateEvent event){
        if(event.entity.getItemInUse().getItem() == ModItems.nileBow){
            event.newfov = 2f;
        }
    }
And it still doesn't work
}

coolAlias · January 24, 2015

That's still not how events work... please read a tutorial.

NovaViper · January 24, 2015

How is not an event? Thats how most of my events on my mod are.

Config Event

public class ConfigEvent {

   @SubscribeEvent
   public void onConfigurationChangedEvent(ConfigChangedEvent.OnConfigChangedEvent event){
	   if(event.modID.equalsIgnoreCase(Constants.modid))
	   {
		   ConfigHandler.loadConfig();
	   }
   }

}

My main class

    @EventHandler
    public void preInit(FMLPreInitializationEvent event){
        ConfigHandler.init(new File(event.getModConfigurationDirectory().getAbsolutePath() + File.separator + channel + File.separator + Constants.modid.toLowerCase() + ".cfg"));
        FMLCommonHandler.instance().bus().register(new ConfigEvent());
   		
        FMLCommonHandler.instance().bus().register(new PlayerEvents(Constants.version, "ZeroQuest", false));
    	Log.info("-----PRE-CONTENT LOAD INITATING-----");
    	Log.info("Loading Main Stuff...");
        this.ZeroTab = new ZeroQuestTab(CreativeTabs.getNextID());
    	if(Constants.DEF_DARKLOAD == true){
   		this.DarkTab = new DarkQuestTab(CreativeTabs.getNextID());
    	}
	NetworkRegistry.INSTANCE.registerGuiHandler(Constants.modid, proxy);
    	Log.info("Load Stuff Loaded Successfully!");		
    	Log.info("-----PRE-CONTENT LOAD FINISHED-----");
    	}

NovaViper · January 24, 2015

I think so, but here is the main class:

	@EventHandler
    public void load(FMLInitializationEvent event)
{			
	Log.info("-----CONTENT LOAD INITATING-----");
    	nileEssence = EnumHelper.addToolMaterial("NileEssence", 4, 4000, 20.0F, 4.0F, 30);
    	
    	Log.info("Loading Block, Recipes and Items...");
    	ModBlocks.load();
        FMLCommonHandler.instance().bus().register(new FOVEvent());
    	ModItems.load();
       	ZeroQuestCrafting.loadRecipes();
    	Log.info("Blocks, Recipes and Items Loaded Successfully!");

    	Log.info("Loading Entities and Ore Dictionary...");
    	ModEntities.loadCreatures();
    	ModEntities.loadOthers();
   	....

Which bus should I register it to if this one is incorrect?

It seems to be called now but it crashes when I enter a world:

1)

java.lang.NullPointerException
at common.zeroquest.events.FOVEvent.FOVUpdate(FOVEvent.java:14) ~[FOVEvent.class:?]

Something is null on line 14 in the FOVEvent class.

2)

if(Constants.DEF_DARKLOAD == true)

What..?

NovaViper · January 24, 2015

the Constants.DEF_DARKLOAD line is a configuration piece that toggles the dark elements (like the dark bow), and now it works but here are the issues now:

1. The zoom is way too fast

2. The arrows just drop infront of me despite I pull the bow at full power.

What I have so far:

Event

public class FOVEvent {

@SubscribeEvent
    public void FOVUpdate(FOVUpdateEvent event){
	if(event.entity.getItemInUse() != null){
		if(event.entity.getItemInUse().getItem() == ModItems.nileBow){
			event.newfov = 2.0f;
		}
		if(Constants.DEF_DARKLOAD == true){
			if(event.entity.getItemInUse().getItem() == ModItems.darkBow){
				event.newfov = 2.0f;
			}
		}
	}
}
}

Bow Class

public class ItemNileBow extends ItemBow
{
public String elementType;

    public ItemNileBow(String type, int damage) 
    {
    	elementType = type;
        this.setMaxDamage(damage);
    }
    
    @Override
    public ModelResourceLocation getModel(ItemStack stack, EntityPlayer player, int useRemaining)
    {
        ModelResourceLocation modelresourcelocation = new ModelResourceLocation(Constants.modid + ":" + elementType + "_bow", "inventory");

        //System.out.println(player.getItemInUse() +":" + useRemaining); USE FOR DEBUGGING ONLY
        
        if(stack.getItem() == this && player.getItemInUse() != null)
        {
            if(useRemaining >= 71987)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid + ":" + elementType + "_bow_pulling_0", "inventory");
            }
            else if(useRemaining > 71980)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid + ":" + elementType + "_bow_pulling_1", "inventory");
            }
            else if(useRemaining <= 71976 || useRemaining >= 71976)
            {
                modelresourcelocation = new ModelResourceLocation(Constants.modid + ":" + elementType + "_bow_pulling_2", "inventory");
            }
        }
        return modelresourcelocation;
    }
}

1 - trace back the references and look at the default usage

2 - are you SURE you're at full power? (did you debug this?)

Ok, I fixed the arrows dropping by reversing the FOV, but how I do I make it gradually move?

Here is what I did

	@SubscribeEvent
    public void FOVUpdate(FOVUpdateEvent event){
	if(event.entity.getItemInUse() != null){
		if(event.entity.getItemInUse().getItem() instanceof ItemNileBow){
			event.newfov--;
		}
	}
}

Ok, I didn't see that it was inside the class and thanks! That works perfectly!

Are you using Eclipse to develop?

If so: right click on a class, or member, or method, then go to References -> Workspace

follow the thread as far as you need to go until you understand the code. This assumes you have the decomp workspace setup and the Forge project in your workspace.

This technique is pretty much how I find where things are called from, what uses what else, and how stuff is done.
